I repeated it yesterday, here on Twitter, from memory, with only a few trivial mistakes, e.g. a “this” for “an” and such.
And that’s only because I LIKE IT.
We have 100 people, and I tell 10 of them “Black swans were discovered in Australia.” I have all 10 of them repeat it back to me and to each other. Then they tell the next 10, then the next 10.
Odds it gets to the end? 100%
